9.2.2.2 IGMP Snooping Version
The membership reports sent to the multicast router are sent based on the IGMP
snooping version of the interface. If you statically specify the version on a certain
interface, the reports are always sent out only with the specified version. If you do not
statically specify the version, and a version 1 query is received on the interface, the
interface dynamically sends out a version 1 report. If no version 1 query is received on
the interface for the version 1 router present timeout period (400 seconds), the interface
version goes back to its default value (3).
To specify the static IGMP snooping version, use the following command.
ip igmp snooping version <1-3>
Configures the IGMP snooping version globally.
1-3: IGMP snooping version (default: 3)
ip igmp snooping vlan VLANS
version <1-3>
Configures the IGMP snooping version on a VLAN
interface.
VLANS: VLAN ID (1-4094)
To delete the specified static IGMP snooping version, use the following command.
no ip igmp snooping version
Deletes the specified IGMP snooping version.
no ip igmp snooping vlan
VLANS version
Dynamic IGMPv3 snooping is configured by default.
9.2.2.3 IGMP Snooping Robustness Value
The robustness variable allows tuning for the expected packet loss on a network. If a
network is expected to be lossy, the robustness variable may be increased. When
receiving the query message that contains a certain robustness variable from an IGMP
snooping querier, a host returns the report message as many as the specified robustness
variable.
To configure the robustness variable, use the following command.
ip igmp snooping robustness-
variable <1-7>
Configures the robustness variable. (default: 2)
ip igmp snooping vlan VLANS
robustness-variable <1-7>
Configures the robustness variable on a VLAN.
VLANS: VLAN ID (1-4094)
To delete a specified robustness variable, use the following command.
Deletes a specified robustness variable.
